4680:
4681: Tags Default Definition Module
4682:
4683: This is part of the LearningOnline Network with CAPA project
4684: described at http://www.lon-capa.org.

4694:
4695: =item image_replication()
4696:
4697: =item resize_image()
4698:
4699: Get correct sizing parameter for an image given
4700: it's initial ht. and wid. This allows sizing of
4701: images that are generated on-the-fly (e.g. gnuplot)
4702: as well as serving as a utility for image_size.
4703:
4704: Parameter:
4705: height_param
4706: width_param - Initial picture dimensions.
4707: scaling - A scale factor.
4708: parstack, - the current stack of tag attributes
4709: from the xml parser
4710: safeeval, - pointer to the safespace
4711: depth, - from what level in the stack to look for attributes
4712: (assumes -1 if unspecified)
4713: cis - look for attrubutes case insensitively
4714: (assumes false)
4715:
4716: Returns:
4717: height, width - new dimensions.

4731: =item recalc()
4732:
4733: Converts a measurement in to mm from any of
4734: the other valid LaTeX units of measure.
4735: If the units of measure are missing from the
4736: parameter, it is assumed to be in and returned
4737: with mm units of measure

4742:
4743: Wrap image 'stuff' inside of the LaTeX required to implement
4744: alignment:
4745: align_tex_image(align, latex_rendering, image)
4746: Where:
4747: align - The HTML alignment specification.
4748: latex_rendering - rendering hint for latex.
4749: image - The LaTeX needed to insert the image itsef.
4750: width,height - dimensions of the image.
4751: Returns:
4752: The 1/2 wrapped image and the stuff required to close the
4753: wrappage. This allows e.g. randomlabel to insert more stuff
4754: into the closure.
4755:
4756:
4757: =item is_inside_of($tagstack, $tag)
4758: This sub returns true if the current state of Xml processing is inside of the tag.
4759: Parameters:
4760: tagstack - The tagstack from the parser.
4761: tag - The tag (without the <>'s.).
4762: Sample usage:
4763: if (is_inside_of($tagstack "table")) {
4764: I'm in a table....
4765: }

1.447 raeburn 4767: =item clean_docs_httpref($href,$docuri,$cdom,$cnum)
4768: HTML pages uploaded to a course which contain dependencies either from iframes,
4769: javascript files or objects (FlashPlayerSwf, MediaSrc, XMPSrc, ConfigurationSrc,
4770: and PosterImageSrc) for which dependency is another file uploaded to the same
4771: course.
4772:
4773: Required input:
4774: href - dependency (either a relative URL, or an absolute URL)
4775: Optional inputs:
4776: docuri - URL of HTML page containing the dependency
4777: cdom - Course domain
4778: cnum - CourseID
4779:
4780: Output:
4781: returns an absolute URL constructed from the href provided, and the calling context.
1.454 raeburn 4782: (this will be null, if the URL does not begin: /uploaded/$cdom/$cnum/docs/ or
